Distance/ Time which means Distance is on horizontal and time is on vertical
Answer:
A - They are both electromagnetic waves.
Explanation:
Electromagnetic waves are waves consisting of periodic oscillations of electric and magnetic fields, that vibrate in a plane perpendicular to the direction of propagation of the wave (for this reason, they are said to be "transverse waves").
Electromagnetic waves, unlike mechanical waves, can travel through a vacuum, and do not need a medium to propagate. Their speed in a vacuum is a constant and it is called speed of light (
).
Electromagnetic waves are classified, depending on their wavelength and frequency, into 7 different types - together they form the electromagnetic spectrum. The 7 types, listed from shortest to longest wavelength, are:
gamma rays
X-rays
ultraviolet radiation
visible light
infrared radiation
microwaves
radio waves
All these waves, despite having different properties, are all electromagnetic waves -so we see that both radio waves and gamma rays belong to this type of waves.
The correct answer is - federal government system.
Even though all of the countries in the European Union are separate countries and they all have their own governments, still the European Union has authority over them. The European Union has its own parliament, and one of the main conditions for every country member is that it obliges to respect and implement the decisions of this parliament, thus losing little of their sovereignty in the process. This is pretty much the same principle used in the federal government systems, where all states have their own leaders and have big authority in their own borders, but also have to obey the commands and decisions of the central government.
The answer would have to be 8.47 m/s/s because the backwards pull + the rate of speed it is going would have to be added to get the answer to compensate for the backwards pull
